Struct RingBuf 

pub struct RingBuf<T: Clone> { /* private fields */ }

Fixed-capacity ring buffer. Oldest entry is dropped when full.

Implementations

impl<T: Clone> RingBuf<T>

pub fn new(capacity: usize) -> Self

pub fn push(&mut self, value: T)

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn capacity(&self) -> usize

pub fn iter(&self) -> impl Iterator<Item = &T>

Returns a slice-like iterator over all values in insertion order.

pub fn to_vec(&self) -> Vec<T>

Collect into a Vec for use with ratatui Sparkline (which needs &u64).
